KINDS OF TRANSPORTATION

1. There are three main kinds of transportation: land, water and air. Each has advantages and disadvantages. For example, trucks and trains can operate in storms that may ground airplanes or keep ships in harbors. Weather and geographical conditions may also determine the type of transportation used in a region. 2. On land the chief forms of transportation are automobiles, railroads, trucks and pipelines. Automobiles provide the most important means of passenger travel in the USA and Canada. The automobile also is important in land transportation in Western Europe and some other parts of the world. Railroads haul about half of the freight and pipeline transport a little less than a fifth. 3. Other means of land transport include buses, streetcars, electric elevated trains, subway trains, motorcycles, etc. Buses serve as a main means of transporting people between cities in many parts of the world and also within larger cities and towns. People in some countries use motorcycles, motor scooters and bicycles as widely as Americans use automobiles. 4. On water transportation follows chief routes: on lakes, on rivers and across oceans. The USA and Canada are the only countries with the advantage of a system of inland waterways like the Great Lakes. River transportation provides cheap, efficient water transportation for much of the heart of the country. Ocean serves as the main artery of transportation between continents. 5.
